tunnels in the guano and stony soil. Tliey appear, to some extent at least, to 
feed upon the tick described below, as Dr. Murphy notes the frequent 
finding of the shriveled remains of the latter in the spiders' tunnels. 
This species is distinct from the other known American species in the 
spining of the legs. Somewhat suggesting the Bolivian D. tovarensis, it is 
a larger species with tibia II unarmed behind instead of bearing three 
spines as on the anterior face, femur I bearing but one spine above in- 
stead of three or four with one on anterior face, metatarsus I\^ armed at 
distal end instead of leg I\' being wholly unarmed, etc.

Carapace, sternum and legs fulvous to light brown, occasionalh of

Medians contiguous, the laterals subcontiguous, .separated form medians 
by a distance a little le.ss than the line of the latter (ratio of distances at 
most as 5:6). Claws of legs I, II, III, and I\' with rcs])ectively eleven, 
ten, .six and five teeth on anterior claw. In the pal])us of the male the 
tibia is thickened and swollen out \-entrall\- somewhat as in nifcsciis but 
proportionately much longer than in that form; the length being fulh' 
twice the greatest thickness. The tarsus is l)roadl>- ovate, distally ob- 
tusely rounded. Spine of bulb long and evenly curving, narrowing di.stad 
and becoming slender and ])ointed. (See figs. 4 and 5.)
